If you know two points on a line, how can you find the rate of change of the variables being graphed?

Answers

Answer 1

Answer: Count the difference of the x values between the two points (the run of the slope) and the difference of the y values between the two points (the rise of the slope). That would get you the rate of change, or slope, of the line.

What is 902.631 rounded to the nearest hundredth?

Answers

Decimals are weird because unlike whole numbers they don't have a ones place. So the number after the decimal (6) is in the tenths place, then hundredths, then thousandths, and so on. So to round to the hundredths place (the 3) we would look at the thousandths place (the 1). If that number is 1,2,3,or4 you drop it and the rest of the number is the same. If it's 5 or up you would add one to the hundredths place. In this case it's a 1 so we drop it and the answer is 902.63 :) hope this helps

902.63
You can see this by looking at the hundredth. (in this case 1) and since it is less than 5 you keep the number the same. So you end with 902.63

Can someone please help me ? I would greatly appreciate it ! Thank you in advance

Answers

X= 96
Y=84

a straight line equals 180 so you just subtract that number from it for X, for Y the diagonal number is equal so its just the same as the one acrossed from it
